This is an excellent game on many fronts. The AI does a great job. It varies from game to game and is not easy to predict at any given time. The graphics are excellent and the game controls are easy to learn. Every time I play I enjoy the experience. The lack of a fifth star is due to the inability to change troop formations (for example you can't create skirmishers and if you change destinations for troops they switch from road column to battlefront and back slowing them down) and some inaccuracies (IMHO). A brigade charging an unsupported battery should be able to take it (don't try it!). Flank and rear fire does not seem to have the devastating effect you would expect. I love this game!
